I'm learning how to finish wood projects with different types of oil-based finish. I was recommended to use this type of soap to clean dirt off finished wood. Since this type of product is not available in Thailand, I will have to make it myself and it's a good excuse for me to try soapmaking.

Does anyone have a recipe to share? Pointing me to the sources would be much appreciated. Here's the soap that was recommended to me:

DESCRIPTION
Linseed soap is made from cold-pressed raw, purified linseed oil and water. It is a pure natural product, without any additives.

SOME WAYS TO USE
FOR PAINT BRUSHES AND HANDS

Mix soap with a little water. Work into brushes and rinse.

FOR WOODEN FLOORS
Add about 1/2 cup of the soap to a bucket of water. Scrub and dry.

Hi @spazelpoof, and welcome!
I have made linseed oil soap and am happy to share the recipe. But there's more too it than just a recipe. The process, while easy enough for experienced soapers, it may be challenging to one who has never made soap before. Here is a link to learn more about the process. Be sure to read Post #2 the link to the Tutorial which lists equipment needed and safety precautions. :thumbup:

Basic Beginner Liquid Soap

Also, you will need to find sources for
Boiled linseed oil
KOH (Potassium Hydroxide)
Distilled water

You need an online calculator to determine the amount of lye (KOH) needed to make a batch.
http://www.soapcalc.net/calc/SoapCalcWP.asp

It is best to make a small 500 gram trial batch before attempting a "normal" batch. Using the calculator above, enter the following into the boxes provided:

Click the "Calculate" button. Then click the "View Recipe" button to take you to the next page to see how much KOH & the water amount you need to make the lye solution. Under "Notes" I wrote the amount of water needed for the dilution phase.

Hello @Zany_in_CO. How are you? Just thought to ask if you like the Linseed liquid soap you made? What does it feel like in liquid soap?

LS seems to be my thing now as I can make 100ml body/hand wash and enjoy any FO I want without waiting 6/8weeks 😁

I just got 1litre bottle of Linseed oil and I am thinking I should use some of it in liquid soap.

Hiya @Saponificarian! I'm well, thanks for asking. I hope you are the same! It's funny you should ask. I had a long chat with a Colorado soapmaker the other day. We haven't seen each other in years! We had a lot of catching up to do. Talked for a hour and a half! One thing she said that surprised me. She said that the soap I made that she liked best was the linseed oil LS for wood. (Murphey's dupe!) She used it to wash her wood floors and all the wood cabinets & window ledges in her house. You should definitely try it. Make a small batch because it lasts a long time. Here's how to use it:

LINSEED OIL SOAP FOR WASHING WOOD:
Better Basics for the Home, by Annie B. Bond (Three Rivers Press, 1999).

If you are lucky enough to have soft water, a new floor soap-and a vegetable oil soap with linseed oil--You can add some fragrant herbal antibacterial tea such as peppermint or lavender, as well as a few other ingredients I like for wood, such as vinegar or lemon juice because it pulls dirt out of wood so beautifully. Here is my favorite floor cleaning formula:

1/8 cup linseed soap or vegetable-oil soap (detergent)
1/4 to 1/2 cup vinegar or lemon juice
1/2 cup fragrant herb tea
2 gallons warm water

Combine ingredients in a pail or bucket. Swirl the water around until it is sudsy. Proceed as normal.

Thank you for the recipe. Is it nice as a body soap?
You're very welcome! I wouldn't say "nice" exactly because the odor of Linseed Oil is similar to Turpintine! I washed my hair with it on impulse and liked it. I later developed a liquid shampoo using Flaxseed oil, Coconut oil & Rosin which is one of my favorite shampoos, although the scent takes some getting used to.

Zany's Flaxseed (aka Linseed) Shampoo

NOTE: ROSIN saponifies much like an oil but without any resulting glycerin. It gives a smooth cold cream finish to the lather and also acts as a detergent and preservative. To calculate - Rosin has the same SAP value as Wheat Germ Oil. (NOTE: May cause contact dermatitis in sensitive individuals).

Here's the recipe I copied off the YouTube site for those who may be interested:

55% Linseed / Flaxseed Oil
30% Coconut Oil
10% Stearic Acid
5% Castor Oil
7% Super Fat

NOTE: Linseed Oil (for wood) is available at Home Depot and other similar stores.
Flaxseed Oil (for the body) is available at Vitamin Cottage and Health Food stores.

Flaxseed oil goes rancid pretty quickly, even refrigerated.Make sure to use ROE.

Linseed oil is far more stable.

+1 to maximum rancidity precautions. There is a reason why it is the preferred oil for oil paintings.

But is there really a difference between flaxseed oil and linseed oil? I thought both are synonymous: the oil coming from the seeds of Linum usitatissimum, and it's just a tradition to call it “linseed” when the seeds are addressed, and “flax” when you primarily refer to the fibre (which isn't even that clear; the word “linen” exists too).

Yes. From personal experience using both:

Both flaxseed oil and linseed oil are extracted from seeds of the plant Linum usitatissimu. Flaxseed oil is pure and fit for human consumption; linseed oil goes through a refinement process and may contain additives that improve its paint-cleaning properties.

Source: https://www.sharecare.com/health/flaxseed-oil/difference-flaxseed-oil-linseed-oil

Flaxseeds and Flaxseed Oil are known to be excellent supplements for a healthy heart.

I first used Boiled Linseed Oil back in 1968 to clean, preserve and protect my natural finish teak dining room set. At that time, it was processed with methanol -- aka "wood alcohol" which is toxic if ingested. I used it to formulate a DIY Murphey's Liquid Oil Soap. At that time, the ingredients contained known soaping oils (particularly linseed oil) and was easily duplicated for cleaning wood floors and cabinets. The ingredients have changed since then.

As it happened, on impulse, I tried using it for shampoo. It worked well but I was concerned about the methanol getting into my system. So that's when I switched to Flaxseed Oil to make my favorite Flaxseed & Rosin Liquid Shampoo.

That may be, however, I have never had linseed oil go rancid, but every bottle of flaxseed oil from any market has gone rancid prior to using it all for dietary purposes. (Quality/freshness may vary in markets.)

Good point. Flaxseed oil from the health food store where I buy it has a short shelf life. I wait until I'm ready to make it before buying. Then soap it right away. I've never tasted it.

Here's a link that talks about shelf life and how to store it.
